I blame the government for mis-using 'investment' to mean
'expenditure'.

When I was growing up anything 'invested' in could be re-sold later to
'realise the investment' during bad economic times. Imagine going up
the pawn shop "I've got a bundle of old nurses pay slips. I invested
4 million quid in them last year".
